Safeguarding Location Privacy

Location data is a particularly sensitive type of data because human mobility reveals so much information about our lives. Where we are and where we go defines the blueprint of our lives and divulges our social relationships. Yet in the age of smartphones and location-enhanced services, our location data is increasingly exposed to untrusted and sometimes untrustworthy third parties. The broad goal of this project is to understand salient threats to location privacy in our daily lives, as well as to design and analyze techniques to preserve privacy when sharing location data.
